dt-bindings: mmc: renesas,sdhi: Document RZ/G2L family compatibility

- RZ/G2UL and RZ/Five ("r9a07g043")
- RZ/G2L(C) ("r9a07g044")
- RZ/V2L ("r9a07g054")
- RZ/G3S ("r9a08g045")
- RZ/V2M ("r9a09g011")

The SD/MMC Interface in the above listed SoCs is not identical to that of
R-Car Gen3. These SoCs have HS400 disabled and use fixed address mode.
Therefore, we need to apply fixed_addr_mode and hs400_disabled quirks.

Document 'renesas,rzg2l-sdhi' as a generic compatible string for the
above SoCs.

Also now use the 'renesas,rzg2l-sdhi' string in the if check for making
sure the required clocks are present.

dt-bindings: Drop redundant minItems/maxItems

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

Properties in if/then schemas weren't getting checked by the meta-schemas.
Enabling meta-schema checks finds several errors.

The use of an 'items' schema (as opposed to the list form) is wrong in

to use in the case of multiple entries.
